A few quick questions about themes and kernals

So I decided to theme my Inc using the red theme posted here on the forums, everything went smoothly but I wanted to change it. So I did a nandroid restore and installed the detox theme with the droid x framework. But the red theme is still there in some areas (see screen shots). How would I remove the red and just put it back to stock? I still have 1 more nandroid backup that I haven't tried, It is the one that I first made right after I rooted. Would that work?

Also, could I just apply themes over themes with doing a nandroid backup (same with kernals)?
